My client owes $26,500 per quarter in federal taxes, 8K state tax quarterlies.

In the irs.gov payment link, is it possible to schedule the quarterly payments ahead of time for the entire year?

He forgot the 2nd quarter, and is pissed about the minimal penalty for doing it late.

BTW, I hand out social security withholding vouchers by the dozens. It's super easy to arrange the federal withholding for elderly clients whose income is largely from investments. This particular client has a big IIRMA deduction, I will check to see how much is left for federal withholding, but out of the 100K annual tax, this will not make much of a dent. On the other hand, he will feel less bad in writing those big checks. Of course, he detests the govt.
